![]() Debian's gcc-13 [1] throws the following error in
kvaser_usb_hydra_cmd_size():
[1] gcc version 13.0.0 20221214 (experimental) [master r13-4693-g512098a3316] (Debian 13-20221214-1)
| drivers/net/can/usb/kvaser_usb/kvaser_usb_hydra.c:502:65: error:
| array subscript ‘struct kvaser_cmd_ext[0]’ is partly outside array
| bounds of ‘unsigned char[32]’ [-Werror=array-bounds=]
| 502 | ret = le16_to_cpu(((struct kvaser_cmd_ext *)cmd)->len);
kvaser_usb_hydra_cmd_size() returns the size of given command. It
depends on the command number (cmd->header.cmd_no). For extended
commands (cmd->header.cmd_no == CMD_EXTENDED) the above shown code is
executed.
Help gcc to recognize that this code path is not taken in all cases,
by calling kvaser_usb_hydra_cmd_size() directly after assigning the
command number.
